hot936spd

im selling my 93z 6spd, and im thinking on an ls1, i mean i got rockers , shorties, 4:10 and the basic bolt ons, ive heard a stock ls1 will be the same as what I got or even slower, i was just wondering what you ls1guys think, I mean im only gonna be able to afford like a 98 or 99, long as its a 6spd. what kinda track times are you guy looking at, with just stock, ls1s, or maybe some exhaust n gears, ??? im confused on what to get, but ive heard like the 01 n up ls1s got the ls6 intake and thats why they are faster. somebody shed some light on the subject for me please. , i mean would a 98 ls1 with like 70 or 80k, 6spd run like my modded lt1, with like exhaust n gears????

MasterEvilAce

the question is.. if you GOT an ls1.. would your current mods FIT?

I'm not even remotely sure about all of the stuff in 4th gens.. but if your mods will fit on an LS1.. then LS1 + your mods > LT1 + your mods...

not sure how much different an LT1 is..

I assume you have never driven an F-body with a LS1 engine in it. Go drive one and you will be hooked. Completely stock they will run mid to low 13s. With a lid, cutout and traction tires they run 12s all day long and still get 20 mpg around town and almost 30 mpg on the highway.

ok, well here it is ok someone i know has 94 6spd, with rockers, pully , midlengths plus 4:10sand a tune thats it for mods, he was on et streets, right, raced a 98 ta 6spd with all this work done to it, he had nittos on, now i heard this guys cut out, and i saw his headers. he clamed 4:10 gears head cam work but i doubt it, the 94 busted his *** from dead stop and from a 2nd gear roll, maybe this guy couldnt drive, then i know someone with an 02 6spd, right, he has cold air, muffler, n 4:10s and runs like 8.18s in the 8th mile, that car freakng rolls. i mean the dude with the 94 runs like 8.30s on street tires, im just wondering, how ls1s comapre to lt1, anyone used to have an lt1 that now has an ls1 pleas let me know something, thanks a lot guys

i'll give you an unbiased opinion, since i don't own a car with either engine...or a v8 at all for that matter

the ls1 will fall short of the lt1 thru the 1st 2 gears, but at 3rd, it is just all over for the lt1
lt1 has worse gas mileage i believe, but are more fun to drive around town (totally subjective) because of where the torque lies in their powerband-and because of the flat as a board curve
i doubt any of your stuff will fit an ls1 and if you get the ls1 you could just sell that stuff so you could get mods for the ls1
actually, the 4.10 gears will work
me personally, i would spring forthe ls1 but i don't have the money to afford one right now, so i guess that has no bearing on anything

I actually had an LT1 also..and I recently just test drove my first LS1. I was a little disapointed. unvc92camarors is correct. The torque output of an LS1 at low RPM isn't even close to that of an LT1. And the LT1 sounds a lot better, too. However, during my test drive I got to down shift and gun it in 3rd gear and lemme tell you, the LT1 is blown away in that catogory. The upper RPM power the LS1 has is significant and the 3rd gear acceleration is much better in the LS1. Make no mistake about it, the LS1 is a much faster car. And that guy in the LS1 you raced should have beaten you if he had all that work done to it. The LT1 has no chance once you shift into 3rd.

stay w/ the LT1. the car is going to cost u less to buy and the mods cost less too. it isnt worth the extra $$$$ for some top end pull. just my .02

hot936spd

i know my lt1 bolt ons wont fit an ls1, i do know a little bit bout it, lol, but thanks for the responses guys, i would like some more responses. anyone?? ive also been in my friends 95 z, all he has is shorties rockers n some 4:56s and he raced that 02 ls1 with 4:10s, muffler, and air lid, , from a 2nd gear roll, ls1 gave the smack down. but that 95z is and 8:30 car in the 8th mile too. soo, i would love some more feeback anybody.

My son has a 99 Z28 A4. The only engine mods are a used G5 cam and a set of Comp 918 valve springs. Headers, and a LS6 intake are the only other engine mods. He also has a 3800 stall convertor. The car has 85,000 miles on it and the heads have never been off. The car is a full weight daily driver but runs 7.65s in the eighth at the track. Four mods and he has an 11 second quarter mile car. Try that with a LT1.....it'll never happen.

I have owned both engines, I was the proud owner of a 93 LT1 f-body, 6-speed, I loved it. The only mods were shortie headers, high-flow catback, K&N FIPK, Flowmaster 80 exhaust, and I loved the way she ran...
...When she ran right. I got tired of trying to figure that low rpm hesitation btwn 1000-2000rpm, I literally changed everything on the car, from just about all the sensors to every other possibility, all to no avail, I spent about 5K in 2 years trying to figure out the problem. My wife got tired of me being sick & tired of trying to figure out the deal, not to mention changing the Opti 4 times.
But boy, my LT1 sounded great, and once over 2000rpm she took off like a banshee, the SOTP feeling was great!

Now I am an owner of a basically stock 2001SS, black again, 6-speed, the first time I drove it, I thought to myself, "what's so great about these LS1's," and next thing I knew, I was over 100mph in 4th and the car was screaming to go more...

Major difference to me, I would say that the LS1 is far more refined, I mean shoot, it's 8 years newer than the 93, so everything is more updated, it just feels better to me. I would say that the LS1 is much more subtle than the LT1, sort of like a sleeper...I shift more often than with the LT1, and that's quite fine by me, I get that LS1 over 2500rpm full throttle, and that engine screams all the way to redline, and just wants to keep on going, while the LT1 had the hole-shot big time, only to run out of steam after about 4500rpm.

It's kind of like comparing a 4-stroke(LT1) to a 2-stroke(LS1), does that make sense?

I will not go back to the LT1. Great engine, and, the LS1 has much more potential. Sure, aftermarket parts cost more, and, GM will be working on Gen III upgrades for a while, so I'm also thinking future support by GM, while only private parties are doing anything worthwhile on the LT1.

It makes good sense to go for an LS1 as opposed to buying another LT1.

AND, as I have said before, opinions are like a$$holes, everyone has one, and they're all full of SHAT

MasterEvilAce

What?? are you talking about 4-stroke vs 2-stroke engines? That's a pretty bad analogy considering 2-stroke engines don't last very long, and eat up oil (obviously). .. bad fuel usage... more polution..

Carlos01SS

No dude, I'm not being THAT literal, just the SOTP feeling, you know, sit on a CR250, that thing don't get going till the upper rpm's, then it SCREAMS...Get the analogy?

psychocabbage

the 98-00 may fall short but the 01 and 02 (not sure on the 2K models about the cam change) dont seem to have that problem.. I know I am getting almost as good launches as I was with my LT1 with gears...

hot936spd

anyone else, used to have an LT1 and now have an Ls1 , i just need some more replys, thankyou everyone who has replied

dist0rtion_69

My family has had 3 Lt1s:

- I owned a 94 Camaro Z28 with 3.23's, a4, shift kit, cutout, K&N fipk..
- My moms currently owns a 94 t/a with centerforce clutch, 1.6 roller rockers, shorty headers, 4.10 gears, 58mm tb, b&m rippershifter
- My mom used to own a bonestock 94 t/a GT..

I now own the car in my sig. My opinion is that an LS1 m6 with 4.10 gears feels just as fun if not funner than an m6 LT1 in 1st-2nd gear. However, due to plenty of testing between the cars, I have no doubts that the LS1 couldn't pull at least a car from 0-50 on the LT1 and pull even more the higher it gets. However, from a first gear roll, or a second gear downshift.. the LT1 does feel pretty damn nice. I would step up to the LS1.. its a whole different experience. It also saved me a few bucks in gas money and the optispark nightmare.

Peace,
